Checkerboard Effect

The goal is to show a checkerboard effect to make an image uncovered.
It 's basically a script and a good understanding of progamming is required.

⇒ animation ⇐

Move mouse over and outside the scene.

We gonna describe the differents stages right away.

First download an image.

Creating Objects

1 - Set up Movie sizes 500x500. Background color : 3D577E. Frame rate = 50

2 - Insert image so that the upper left corner stands in 0,0.

3 - Draw a square 50x50. Background color : 3D577E.
Anchor point : upper left.
Name it square. Target toggled.
Watch out images :

SwishMax Script

Here is the script for Scene_1

onLoad () 
{
    w = Stage.width;   // scene width
    h = Stage.height;  // scene height
    n = 10;    
    // anchor point square 1
    Xinit = 0;
    Yinit = 0;
    
    // square side
    a = square._width; 
    /* we cover up all scene with
       10x10 squares    */
    for (i=1; i < n*n +1; i++)  
    {      
        duplicateSprite(square, "square"+i, i);
        // 10 a row 
        ("square"+i)._X = Xinit + ((i-1)%n)*a;
        ("square"+i)._Y = Yinit;
         /* 10 reached ; we increase Y
            to get next line of squares   */ 
        if ( i%n == 0 )   Yinit += a ;   
    } 
    // don't need anymore.
    square._visible = false;
}
/*--------------------------------------
    function called every 10ms
    when mouse rolls over scene
    to make vanishing squares
--------------------------------------*/
function vanish(j)
{      
    for (j=1; j < (n+1)*n +1; j++)
    {
       (("square"+j)._xscale >0) ? ("square"+j)._xscale-- : ("square"+j)._xscale = 100;
       (("square"+j)._yscale >0) ? ("square"+j)._yscale-- : ("square"+j)._yscale = 100; 
    }
}
// let's set up a timer
on (rollOver) 
{
    timer = setInterval(vanish,10); 
}
// reset timer and scales
on (rollOut) 
{   
    for (k=1; k < (n+1)*n +1; k++)
    {
       ("square"+k)._xscale = ("square"+k)._yscale = 100;
    }
    clearInterval(timer);   
}

Well, it's pretty basic; you could improve script code.
